7 Claims.

'Ihis invention relates to dispensing 'devices particularly adapted to discharge finely divided material and more particularly to dispensing devices especially designed to discharge granulated soap and to be provided with a hand operated discharge valve that may dispense a predetermined quantity of soap on each operation.

In dispensers of this character, it is highly desirable that the parts be made and assembled in a simple and inexpensive manner so that each installation will represent a minimum investment and will be capable of efcient operation over a reasonable period of time and be relatively inexpensive to maintain. Moreover, it is essential that the structure, which is provided, be capable of discharging the material in a finely divided state and that the material be kept from clogging the valve at the discharge orifice. It seems that prior art devices, although suggesting solutions of one kind or another, incorporated mechanism that failed to solve the problem satisfactorily, and, while these devices were used, 'they were neither simple to manufacture, efficient nor accurate in the control of the discharge of the material.

One of the objects of the invention resides, therefore, in the provision of certain novel features producing advantageous results both in the manufacture and in the use of a dispenser of the character herein disclosed whereby an exceptionally simple and inexpensive structure is provided that is easy to manufacture and maintain, and which eiliciently operates constantly to provide a uniform discharge of material each time the handle is operated.

A further object of the invention resides in the provision of a novel form of cover and locking means therefor in a dispenser of this type and a novel mode of attachment of the bowl to the wall, or other mounting on which it is placed, whereby the usual expensive equipment used heretofore is eliminated and a simple and practical form is provided. l

A still further object of the invention is to provide in a dispenser of the type herein disclosed a novel form of plastic body or bowl and a novel form of valve, agitator and cap therefor, also of plastic material, whereby the valve members and,

an agitator may be seated as a unit in the body and operated by a handle novelly assembled to the valve and projecting through the body, and the cap may be attached by a .simple but effective form of locking means.

The invention is also directed to the specific form oi' valve that is provided at the discharge orifice to control the amount of material dispensed on each operation. Preferably, a plurality of seats are formed in the wall of the bowl to receive a number of relatively movable apertured disks and an agitator all connected as a unit and operated by a handle, certain of the disks being novelly designed to be tightly seated and the movable disk and agitator being loosely seated but connected together so that they will be rotated by the handle to disturb the material and cause it to move first from the apertures of the upper disk in measured amounts through the apertures of the movable intermediate disk to the apertures in the lower disk and then out through the discharge orifice.

Other objects and advantages of the invention will be apparent from the following detail description when taken in connection with the accompanying drawings which form a part hereof.

Fig. 16 is a similar view of the middle disk to illustrate a similar construction and to show partitions. which, in eilect, divide the underside oi the middle disk into separate pockets or compartments; and

Fig. 17 is a similar view oi the lower disk.

The dispensing device illustrated in the drawings comprises a novel form of plastic body or bowl I open at the top and bottom. there being provided a cap 2 for the top and` a valve 3 controlling the amount of material dispensed through the open bottom designated herein as the discharge orince 5. The top edge oi bowl I is formed to provide a reduced upstanding ilange s and 'an outer shoulder 1 for cooperating with an annular recess 8 in the bottom edge of cap 2 and a shoulder 9 for seating upon shoulder 1. 'I'his forms a tightly sealed connection between cap 2 and bowl I to prevent the entrance of moisture that would tend to cause the granulated soap to cake and not ilow freely when valve 3 is operated. Cap 2 may also be made of plastic material so that the tendency oi the plastic ma asoaoic terial to cold flow will keep these cooperating parts in tight relationl to maintain this eiective seal.

A novel form of key operated means III may be used to lock cap 2 in position and prevent unauthorized access to the interior of bowl I. Key means I0 may comprise a novel i'orm o! key II having a pair of diametrically opposed key lugs I2 and I3 adapted to engage in recesses I4 and I5 formed in anl exposed face I6 of a tumbler I1. Tumbler I1 is formed with a head I8 seated in a recess I9 formed incap 2 by molding recess I9 as a depression having walls 20 that extend downwardly and inwardly to support head I3 of tumbler I1. A reduced shank 2l of tumbler I1 is guided by a wall 22 extending downwardly from the inwardly extending wall 20. A plurality of locking lugs 24 are formed on the lower end of tumbler shank 2l to extend transversely to the axis of rotation of tumbler I1. These key lugs 24 are adapted to be arranged in a predetermined pattern, as illustrated in Figs. 3 and 10, and are adapted to be inserted into and through openings 25 of corresponding contour'and pattern that are formed in a frame member 26 having radial arms 21 extending to a peripheral band 28 adapted to be secured by screws 23 to aseoond band 30', both of these band members being seated in an annular recess 3I formed interiorly about the top edge of bowl I. Band 30' may be ilxed in recess 3|' as by cementing or by the use of any suitable mechanical connection. As stated above, cap 2 may be made oi plastic material and may be slightly flexible so that it will yield when key lugs I2 and I3 of key I I are inserted in openings `I4 and I5 of tumbler I1 and the key is pressed downwardly. In this operation, the key is turned until locking lugs 24 are aligned with openings 25 in trame member 26 and are inserted into and through these openin overlapping relation. Connector I0 consists of ings. Further rotation oi key II will bring lugs 24 out of registration with openings 25 below frame member 26. Ii slight ilexibility ci cap 2 ls relied upon during this operation to bring lugs 24 below openings 25 in frame' 26, these lugs 24 will be bindingly held against the underside of frame 26 when the pressure on key II is released and the key is removed. In this manner, cap 2 may be tightly held about the upper edge o! bowl I to provide the pressure in maintaining the aforesaid desirable seal. It will be noted that lugs I2 and I3 of key II may be arranged in any predetermined pattern so that only individuals having key I I may remove cover 2. Even with openings I4 and I5 being disposed diametrlcally opposite each other in head IB o1 tumbler I1. it is impossible to rotate tumbler I1 without a key having lugs I2 and I3 oppositely disposed. The

insertion ot an implement in either opening I4 or I5 will not rotate tumbler I1. Both lugs I2 and I3 must be used in order to secure the necessary rotation oi' tumbler I1' in order to bring locking lugs 24 into registration with openings 25 to permit withdrawal oi' the lugs through these openings and the removal of cap 2.

Valve 3 controls the ilow of the material from bowl I through orice 5. It may comprise a plurality oi apertured disks which, as illustrated specifically in the drawings, include an upper disk 30 having a number of apertures 3i, a middle or intermediate disk 32 having a number of apertures 33, and a lower disk 34 having a number oi' apertures 35. These disks are nested one above the other in a predetermined relation so that apertures 33 of intermediate disk 32 will alternately align or register with either the apertures 3| o! upper disk 30 or the apertures 35 of lower disk 34. Included in this arrangement is an agitator 36 having a plurality of arms 31 extending outwardly to connect with an annular rim 38.

Included as a part of the novel arrangement is the use oi a connecting means 40 adapted to hold these parts together so that they may be inserted and carried in bowl l as a unit. A series oi seats 4I, 42, 43 and 44 are formed in the wall of bowl I to receive these disks and the agitator. As iilustrated in Figs. 1 and 2, these recesses are novelly oiIset with respect to each other and are located near discharge oriiice 5, and disks 30, 32 and 34 and agitator 33 are received in these seats a head 45, a rectangular shank 46 and a lower cylindrical stud 41. Agltator 36 and middle disk 32 are provided with center openings 43 and 43, respectively, each being rectangular cross-sectionally to correspond with the cross-sectional dimensions 0f rectangular shank 46 of connector 40, so that when shank 46 is inserted through openings 43 and 43, agitator 38 and middle disk 32 will rotate together when either is moved l(see Fig. 9). Upper disk 30 is provided with an opening 50 of a diameter larger than the cross dimension of rectangular shank 46, so that the latter may turn in opening 50 without turning upper disk 30. Lower disk 34 is provided with a center opening 5I that may be slightly larger in diameter than the diameter of the lower cylindrical stud 41 of connector 40, so that turning of this connector 43 will not rotate lower disk 34. In order to hold the parts as a unit about connector 0. the lower cylindrical stud 41 may seat in a recess 52 of a collar 53 and a bolt 54 may thread upwardly into connector 43. as illustrated cross-sectionally in Figs. I. and2. Middle disks 32 may be carrying a handle 51 may be seated in this recess 55 and held therein by a bolt 53 adapted to be passed through the handle, its shank 56 threading into an enlarged portion 69 formed on the underside of middle disk 32, as illustrated in Figs. l and 5. Handle 51 may operate in a slot 58' in the wall of bowl I, this handle extending through this slot and being accessible exteriorly for operation, the stroke of this handle 51 being determined by the length of slot 58.

A further nove1 feature of the invention resides in employing, in connection with the connection and arrangement of the disks and agitator as aforesaid, seats 42 and 44 of a size that tightly receives upper and lower disks 30 and 34, so that these disks will be frictionally held against rotation in these seats and in employing seats 4I and 43 of a size that will loosely receive agitator 36 and middle disk 32. Agitator 36 and middle disk 32 rotate together by means of connection 40 when handle 51 is moved back and forth in slot 56'. The construction of connector 40 with respect to the man-ner in which it carries agitator 36 and the three disks 30, 32 and 34 permits upper disks 36 and lower disk 34 to be held tightly upon either seats 42 and 44 and against rotation by this frictional engagement when agitator 36 and middle disk 32 are actuated. Although any other form of seating for the agitati and the disks may be used and even a mechanical connection employed to prevent movement of the upper and lower disk 30 and 34, the present arrangement affords a very simple and inexpensive construction that eiectively accomplishes its purpose and provides a structure capable of eilective operation over a period of time without experiencing wear and requiring repairing.

Inasmuch as agitator 36 and disks 30, 32 and 34 may also be molded of plastic material, apertures 3|, 33 and 35 are provided with downwardly extending annular wallsl 60, 6I and 62, and the disks may be provided with downwardly extend-L ing peripheral flanges that rest upon these seats d2, 43 and 44. The depth of the peripheral ange of each disk and the depth of the apertures of flanges 60, y6I and 62 depend upon the relative depth of disks 30, 32 and 34. The volumetric capacity of aperture 33 and the number employed in middle disk 32 determine the quantity of material discharged by each operation of handle 51. It will be observed that the depth of apertures 3| and 35 is not as great as the depth of aperture 33. Itis not necessary that the depth of the apertures of the three plates bear any particular relation to each other because only the amount of soap filling apertures 33 will be discharged by each operation of handle 51. Y

When handle 51 is in the position illustrated in Fig. 7, apertures 33 of intermediate disk 32 register with apertures 3l in top plate 3u and are lled with the granulated soap in bowl I that falls through apertures 3l. Rotation of handle 51 to the position shown in Fig. 6 brings apertures 33 then into registration with apertures 35 of bottom plate 34 so that the material carried by the middle plate in these apertures 33 will drop through apertures 35 in lower plate 34 to the discharge orifice 5. Each movement of handle 51 causes arms 31 of agitator Zit to oscillate and disturb the material within bowl i, it being noted in Fig. 6 that when handle l is in the position bringing apertures 33 into registration with apertures 36, these agitator arms 3l have completed their movement of pushing the material toward and into the apertures 3l of upper disk 3l). If there is any tendency of the material to agglomerate or become lumpy. agitator arms 31 will tend to disturb the material suiiciently to break up the lumps and push the material into apertures 3 I.

A novel type 0f mounting bracket 65 preventing removal of bowl I from its mounting by an unauthorized person is shown in Figs. 2, 3 and 8. Bracket 66 is somewhat rectangular in formation and is provided with a face 66 that may conform to the contour of the surface 61 against which bowl I vis adapted to be mounted. In the drawings, surface 61` is illustrated as flat but it will be understood that it maybe a curved surface or any type, and that face 66 may be made to conform to the configuration thereof. Openings 38 are provided in rear wall 69 of face 55 to receive mounting screws 10. against wall 61 before bowl I .is secured thereto, this being accomplished by screws l0 being inserted in openings 68 from lthe inside of the bracket and then driven into wall 6l. Before this is done, however, bolts 12 are inserted in openings 13 so that their threaded ends extend away from bracket 66 and their heads 14 lie in recesses 16 formed in the front face 66 of wall 69. Bowl i is then mounted by passing the projecting threaded ends of bolts 12 through openings 16in the wall of bowl I. Wing nuts 11 are then threaded into position to hold bowl I upon these bolts 12. It will be noted that these wing nuts 11 must be threaded upon bolts 12 while cover 2 is removed. In this way, it is impossible to remove bowl I without the use of key Ii which locks the cover in position.

A feature that may be provided in connection with the key means heretofore described is the use of stop means 30 that will prevent key II from being turned too far and allow each locking lug 24 to align with the next opening 25, which4 might cause these lugs to snap free without effecting a locking operation. This locking means comprises shoulders Von the lower face of frame 26 serving to restrict the movement of key I I, and hence, lugs 24, to a clockwise direction, when cap 2 is locked in position, so as to prevent each lug 24 from moving into the next opening 25. Thus, the key II may be turned clockwise to effect locking but limited in its movement by these lugs 33 and moved counterclockwise to eect unlocking.

Although it is not essential tovarious novel features of the invention, it will be noted that the structure described may be novelly made of plastic parts except for such parts as screws 26, 54, 53, 'la and l2. Thus, the use of metal is reduced to 'a minimum and the cost of labor in the assembly of the parts has likewise been reduced' to a minimum because the plastic parts have been molded in a manner to eliminate much of the assembly time heretofore required when the parts were made of metal.

A further eembodiment of the invention is illustrated in Figs. ll toll?, inclusive. The agitator 33 of this form is molded in the form of a plurality of radially extending legs 9i having their ends flared as indicated at 92. In cross section, each leg 6I is somewhat triangular.

One of the faces forms the base and the other two faces form the side faces of each leg, so that, when the agitator is moved it will effect a sweeping action to push the soap into the path of openings 94 of top plate 65. Upstanding pins 96 are also provided `upon legs 9i to break up the granules oi soap that may tend to cake in the Bracket 65 is mounted area surrounding the agitator. A middle plate 81 and a lower plate 88, together with top plate 85, serve to comprise the valve assembly that is adapted to be mounted in the bottom of bowl 88 of this embodiment. As illustrated in Figs. 12 and 13 seats |00, IOI, |02 and |03 similar to seats 4| to 44, inclusive, are formed on the inside wall of bowl 88 to receive agitator 80 and disks 85, 81 and 88. Instead of relying upon a Irictional grip, I prefer in this instance to use vertical ribs |04 disposed in spaced relation' about the'periphery of top plate 85 and similar ribs |05 about the periphery of bottom plate 88 that will lie in grooves |08 and |01 formed in seats |0| and |03, respectively, as shown in Fig. 13. Thus, it is apparent that either frictional or mechanical means may be used to keep top and bottom plates 95 and 88 from rotating when handle |08 is oscillated in its slot in the wall of bowl 88.

A connector |08 similar to connector 40 is used to hold these plates and the agitator together. Central opening in top plate 85 is circular and larger in diameter than the square shank portion of connector |08.` Central opening ||2 in agitator 80 and central opening ||3 in middle plate 8l are square and receive square shank portion of connector |08 in driving relation whereby rotary movement imparted to this middle plate 8l by operation of handle |08 will be transmitted to the agitator and cause the same to rotate with the middle plate. Central opening H4 in bottom plate 88 is larger in diameter than the diameter of the reduced cylindrical portion I5 of shank |08 so that with upper plate 85 this bottom plate will not rotate but will remain locked to the wall of the bowl by the ribs |04 and |05 lying in grooves |08 and |01. A cap ||8 fits over the terminal of the reduced portion ||5 and a screw passes through this cap and threads 'into this reduced portion.

Upper and middle plates 85 and 81 are in a position as shown in Figs. 11 and 12 with openings 84 in upperplate 85 registering with openings.| I8 in middle plate 81 and dispensing therefrom a charge of soap into the latter openings. Movement of the middle plate 8l by actuation of handle |08 brings these-latter openings ||8 into register with openigs |20 in bottom plate 88, as shown in Fig. 13, whereupon the charge of soap is allowed to drop to and through the open bottom of the bowl. Figs. 15, 16 and 17 are bottom views of the three plates. They illustrate the construction of these plates and show particularly the ange and web arrangement employed on the bottom side. Openings 84 and ||0 have flanges upon the depth of anges |24 of openings I|8 of the middle plate. These ilanges |24 form in fact pockets |81 which are filled each time they are moved to register with openings 84 in the upper plate. The soap in these pockets is then carried over the upper face of the lower plate until the pockets register with openings |20. It will be apparent from Fig. 13 that it will be easy for soap to accumulate between the upper and middle plates. To prevent clogging, openings |40 smaller than openings ||8 are provided slightly in advance of the latter and a series of smaller openings |4| are provided about the central portion of the middle plate. Also, to prevent any tendency for soap to pile up against the inside of flange |34 ofthe top plate, a series of small openings |42 are provided in the middle plate.

-Openings |43 and |44 are also provided in the those employed to mount handle |08 and the bowl to the wall substantially in the same manner as ily adapt the same for use under varying condi- |2| and |22 extending the depth of the upper 8] that are connected by webs |28. Openings ||4 and |20 also have flanges |21 and |28 extending the depth of lower plate 88 that are connected by webs |28. In addition to these webs, both middle and lower plates 8l and 88 have spacing walls |30 and |3| which divide the area of these plates into pockets or compartments |32 and |33, respectively. The three plates are also provided with depending annularl skirts or anges designated as |34, |35 and |35.\ The bottom of these anges rests upon the respective seats |0I, |02 and |03, while ribs |04 and |05 of the upper and lower plates are 1 formed upon thefouter surface of flanges |34 and |38.

The amount of the charge that is dispensed upon each operation of handle |08 will depend tions of service, without eliminating certain features, which may properly be said to constitute the essential items of novelty involved, which items are intended to be dened and secured to me by the following claims.
